A) metaphase (:
prophase is when chromatin condenses into chromosomes then the centrosomes move to opposite ends of the cell, anaphase is when sister chromatids separate and then are pulled towards the centrosomes and telophase is the splitting of the cell (v v briefly explained)
Sister chromatids line up at the equator of the cell during the metaphase stage of cell division. This arrangement is essential to ensure each new cell receives an exact copy of each chromosome. The next stage, anaphase, involves the separation of these chromatids. ;
Sister chromatids line up at the equator of the cell during metaphase. This alignment is essential for ensuring that each daughter cell receives an equal set of chromosomes. Therefore, the correct answer is A, Metaphase.
